成分(h-1):平均粒子径が約3μmの石英粉末
成分(i-1):50質量%のカーボンブラックと、50質量%の分子鎖両末端ジメチルビニルシロキシ基封鎖ジメチルポリシロキサンの混合物、粘度2,000mPa・s(ビニル基の含有量:0.23質量%)
硬化性オルガノポリシロキサン組成物を空気循環オーブン内で60℃で1時間熱硬化させることにより、硬化物を得た。デュロメータ測定のため、硬化物を少なくとも6mmの厚さになるよう積層した。25℃での硬化物のショア00硬度を、試験方法ASTM D2240-05(2010)(ゴム特性デュロメータ硬度の標準試験方法)に従って決定した。
18mlの硬化性オルガノポリシロキサン組成物を、直径22mm及び高さ84mmのガラス瓶に注いだ。硬化性オルガノポリシロキサン組成物を、空気循環オーブン内で60℃で1時間硬化させた。次いで、信頼性試験のためガラス瓶内の硬化物を熱衝撃チャンバーに1サイクル(-40℃⇔125℃、-40℃及び125℃でそれぞれ30分間放置)入れた。360サイクルの熱衝撃試験後、硬化物を視覚的に観察した。
本発明による硬化性オルガノポリシロキサン組成物は、硬化して低硬度シリコーンゴムを形成し、硬化中に接触する各種基材に対して優れた初期接着性を示し、優れた熱衝撃安定性を示すため、当該硬化性オルガノポリシロキサン組成物は、モーター制御、輸送機器のモーター制御、発電システム、又は宇宙輸送システム等のパワーデバイス用の封入材又はシーラントとして有用である。
